The Jargon File (version 4.4.7, 29 Dec 2003):

Dissociated Press
 n.

    [play on ?Associated Press?; perhaps inspired by a reference in the 1950
    Bugs Bunny cartoon What's Up, Doc?] An algorithm for transforming any text
    into potentially humorous garbage even more efficiently than by passing it
    through a marketroid. The algorithm starts by printing any N consecutive
    words (or letters) in the text. Then at every step it searches for any
    random occurrence in the original text of the last N words (or letters)
    already printed and then prints the next word or letter. EMACS has a
    handy command for this. Here is a short example of word-based Dissociated
    Press applied to an earlier version of this Jargon File:

        wart: n. A small, crocky feature that sticks out of an array (C has
        no checks for this). This is relatively benign and easy to spot if the
        phrase is bent so as to be not worth paying attention to the medium in
        question.

    Here is a short example of letter-based Dissociated Press applied to the
    same source:

        window sysIWYG: n. A bit was named aften /bee't@/ prefer to use the
        other guy's re, especially in every cast a chuckle on neithout getting
        into useful informash speech makes removing a featuring a move or usage
        actual abstractionsidered interj. Indeed spectace logic or problem!

    A hackish idle pastime is to apply letter-based Dissociated Press to a
    random body of text and vgrep the output in hopes of finding an
    interesting new word. (In the preceding example, ?window sysIWYG? and
    ?informash? show some promise.) Iterated applications of Dissociated Press
    usually yield better results. Similar techniques called travesty generators
    have been employed with considerable satirical effect to the utterances of
    Usenet flamers; see pseudo.
